CVE-2023-41355

Enforces verification of the source of a communication channel by requiring identification and authentication of services first.

Security testing and developer training directly verify and enforce proper input validation, reducing exploitability of injection and malformed-data weaknesses.

Security testing and evaluation at multiple SDLC stages directly detects missing or flawed input validation, with the required remediation process ensuring fixes are applied.

Requires explicit verification of the source and integrity of the channel used for authentication and other security functions.

Provides the means to verify the source of name-resolution responses instead of relying on unauthenticated channels.

Requires explicit verification of the communication source, blocking session hijacking via spoofed or alternate channels.

Directly implements checks on information inputs to reject invalid data before processing.

Spam protection mechanisms perform filtering and detection on inbound/outbound messages, directly compensating for missing or weak input validation of unsolicited content.

Authentication of users/services/hardware directly enforces source verification for communication channels.

Verifying identity assertions prevents spoofed channel origins but does not cover all channel-establishment scenarios.

Network protections reduce unauthorized channel usage but do not specifically require origin verification at channel setup.

Network security controls enforce source verification and channel authentication for incoming communications.

Security of network services includes validating the origin of service requests and connections.

A.8.24 mandates proper use of cryptography (algorithms, key management, protection of data in transit/storage) but has no bearing on whether a product correctly verifies the origin of an incoming communication channel; the weakness can still be present and exploited regardless of cryptographic controls.

A.8.25 mandates security requirements, secure coding guidelines, checkpoints, testing (incl. code scans) and developer training in the SDLC, which reaches a slice of input validation defects but leaves the majority (incomplete enforcement, second-order inputs, parser differentials, post-validation canonicalization) unaddressed as in the SA-3 and A.8.28 anchors.

A.8.26 requires identifying and specifying requirements for resilience against malicious attacks (explicitly naming SQL injection) plus input validation, authentication, segregation of access, output controls, and cryptography; these can address origin verification for expected channels in some (but not all) application designs, leaving a bounded remainder where the weakness is still exploitable.

Security-by-design principles explicitly call for data validation and sanitization at every layer, reducing the chance that malformed or malicious input will be processed without scrutiny.
